hi welcome to HCM
-hi i had gone through your query and understand your concerns. i would come up with the possibility of ANKYLOSING SPONDYLOSIS

-without treating the underlying cause ( Ankylosing Spondylitis
),your walking complaints cant be cured.
-basically it is an autoimmune disease
which affect the your immune system and produce your complaints.
i advise you taking Homeopathic
medicines gives safe and permanent cure for your complaints along with management with physiotherapy
consult your local homeopathic physician for correct diagnosis of the case and remedy to fit your complaints
I hope this is helpful for you, thank you
